+# Credential and access routing
+
+**Audience:** Codex, Claude Code, Grok, and custodian agents that call **llm-connect**
+for inference. Run this check **before** requesting secrets, API keys, SSH access,
+login tokens, or database passwords — in any repo, not only `ops-warden`.
+
+ops-warden **issues SSH certificates only** (`warden sign`, `cert_command`). Every
+other credential need belongs to another subsystem. **Do not** message
+`ops-warden` on State Hub expecting a secret value; the reply is a pointer, not a key.
+
+### Lookup (do this first)
+
+```bash
+warden route find "<describe your need>" --json
+warden route show <catalog-id> --json
+```
+
+Requires the `warden` CLI from `~/ops-warden` (`uv tool install .` or `uv run warden`).
+
+| Agent runtime | How to orient |
+| --- | --- |
+| **Codex / Grok** (shell, HTTP State Hub) | `warden route` commands above; inbox `to_agent=agentic-resources` is for coordination, not secret vending |
+| **Claude Code** (MCP when available) | `get_domain_summary("custodian")` for workstreams; **still** use `warden route` for credential ownership |
+| **llm-connect** (inference service) | Never put secret retrieval in prompts; route custody to OpenBao/operator paths surfaced by `warden route` |
+
+### Quick routing table
+
+| I need… | Owner | ops-warden executes? |
+| --- | --- | --- |
+| SSH cert (`adm`/`agt`/`atm`) | ops-warden | **Yes** — `warden sign` |
+| API key, DB password, provider token | OpenBao (`railiance-platform`) | No — route only |
+| Login / OIDC / MFA | key-cape / Keycloak | No — route only |
+| Authorization decision | flex-auth | No — route only |
+| activity-core → issue-core emission | activity-core + issue-core | No — `warden route show activity-core-issue-sink` |
+| SSH tunnel | ops-bridge (+ `cert_command` from warden) | No — route only |
+
+### Anti-patterns (do not do these)
+
+- `POST /messages/` to `ops-warden` asking for `ISSUE_CORE_API_KEY`, `OPENROUTER_API_KEY`, etc.
+- Inventing `warden secret`, `warden login`, `warden bao`, `warden tunnel` — they do not exist
+- Pasting secrets into Git, State Hub, workplans, logs, or chat
+
+### Other capabilities (reuse-surface)
+
+Non-credential capabilities are usually discovered through **reuse-surface** federation
+(`reuse-surface` registry / `capability.*` indexes). Credential routing is inlined in
+every repo's agent instructions because it is high-frequency, high-risk, and easy to
+get wrong.

+## Session Protocol
+
+Dev Hub (State Hub API): http://127.0.0.1:8000
+MCP server name in `~/.claude.json`: `dev-hub`
+
+**Step 1 — Orient**
+
+Read the offline-safe brief first — it works without a live hub connection:
+```bash
+cat .custodian-brief.md
+```
+Then call the MCP tool for richer cross-domain context when MCP tools are exposed:
+```
+get_domain_summary("infotech")
+```
+If MCP tools are unavailable in the current agent session, use the REST API:
+```bash
+curl -s "http://127.0.0.1:8000/state/summary" | python3 -m json.tool
+```
+If the hub is offline: `cd ~/state-hub && make api`
+
+**Step 2 — Check inbox**
+With MCP tools:
+```
+get_messages(to_agent="agentic-resources", unread_only=True)
+```
+Mark read with `mark_message_read(message_id)`. Reply or act on coordination
+requests before proceeding.
+
+Without MCP tools:
+```bash
+curl -s "http://127.0.0.1:8000/messages/?to_agent=agentic-resources&unread_only=true" \
+  | python3 -m json.tool
+curl -s -X PATCH "http://127.0.0.1:8000/messages/<id>/read" \
+  -H "Content-Type: application/json" -d '{}'
+```
+
+**Step 3 — Scan workplans**
+```bash
+ls workplans/
+```
+For each file with `status: ready`, `active`, or `blocked`, note pending
+`wait`/`todo`/`progress` tasks.
+
+**Step 4 — Present brief**
+
+1. **Active workstreams** for `infotech` — title, task counts, blocking decisions
+2. **Pending tasks** from `workplans/` + any `[repo:agentic-resources]` hub tasks
+3. **Goal guidance** — if `goal_guidance` in summary:
+   - `needs_workplan`: surface as top action — *"Repo goal '{title}' has no workplan yet"*
+   - `alignment_warnings`: flag if active work is not aligned with current goal
+4. **Suggested next action** — highest-priority open item
+5. **SBOM status** — flag if `last_sbom_at` is unset for this repo
+
+If no workstreams: follow First Session Protocol (`first-session.md`).
+
+**During work:** `record_decision()` · `add_progress_event()` · `resolve_decision()`
+
+> State Hub is a *read model*. Bootstrap tools (`create_workstream`, `create_task`)
+> are First Session Protocol only. Work structure belongs in repo files (ADR-001).
+
+**Session close:**
+With MCP tools:
+```
+add_progress_event(summary="...", topic_id="f39fa2a3-c491-414c-a91b-b4c5fcc6139c", workstream_id="<uuid>")
+```
+Without MCP tools:
+```bash
+curl -s -X POST http://127.0.0.1:8000/progress/ \
+  -H "Content-Type: application/json" \
+  -d '{"topic_id":"f39fa2a3-c491-414c-a91b-b4c5fcc6139c","workstream_id":"<uuid>","event_type":"note","summary":"what changed","author":"codex"}'
+```
+If workplan files were modified, ensure the local copy is up to date first:
+```bash
+git -C <repo_path> pull --ff-only
+cd ~/state-hub && make fix-consistency REPO=agentic-resources
+```
+For repos where implementation runs on a remote machine (e.g. CoulombCore),
+use the combined target which pulls before fixing:
+```bash
+cd ~/state-hub && make fix-consistency-remote REPO=agentic-resources
+```
+**C-15** (DB task ahead of file) is normal in multi-machine workflows — writeback
+will sync the file to match DB.  **C-16** (repo behind remote) blocks all writes
+until you pull — intentional to prevent clobbering remote progress.

+
+File location: `workplans/AGENTIC-WP-NNNN-<slug>.md`
+ID prefix: `AGENTIC-WP-`
+
+Work items originate as files in this repo **before** being registered in the hub.
+
+Canonical workplan/workstream frontmatter statuses are:
+`proposed`, `ready`, `active`, `blocked`, `backlog`, `finished`, `archived`.
+Use `proposed` for a newly drafted plan, `ready` after review against current
+repo state, and `finished` when implementation is complete. `stalled` and
+`needs_review` are derived health labels, not stored statuses.
+
+Closed workplans may be moved to `workplans/archived/` with a completion-date
+prefix: `YYMMDD-AGENTIC-WP-NNNN-<slug>.md`. The frontmatter id remains
+unchanged; the prefix is only for quick visual reference.
+
+Small opportunistic tasks discovered during another session use **Ad Hoc Tasks**:
+`workplans/ADHOC-YYYY-MM-DD.md`, workstream slug `adhoc-YYYY-MM-DD`, and task ids
+`ADHOC-YYYY-MM-DD-T01`, `T02`, etc. Use adhocs only for low-risk work completed
+directly. Promote anything requiring analysis, design, approval, dependencies, or
+multiple planned phases into a normal workplan.
+
+Ecosystem todos from other agents arrive as `[repo:agentic-resources]` hub tasks —
+visible at session start. Pick one up by creating the workplan file, then registering
+the workstream.
+
+Task blocks use this shape:
+
+```task
+id: AGENTIC-WP-NNNN-T01
+status: wait | todo | progress | done | cancel
+priority: high | medium | low
+state_hub_task_id: "<uuid>"         # written by fix-consistency — do not edit
+```
+
+Status progression is `todo` → `progress` → `done`; use `wait` for waiting or
+blocked work and `cancel` for stopped work.

+# Infrastructure Friction Assessment
+
+*Generated 2026-06-07 from captured coding-session data (Helix Forge session
+memory), after the Detect-hardening pass ([AGENTIC-WP-0005]). First data-driven
+assessment of where our agentic coding sessions spend effort on plumbing rather
+than work.*
+
+## Method & data quality
+
+- **Corpus:** 72 sessions captured across Claude + Grok. A session-quality filter
+  ([detect/quality.py]) drops health-checks, smoke-tests, and interrupted runs
+  (mostly `llm-connect` *"Say hello in one word"*). **27 are real coding sessions.**
+- **Caveat:** the 41 % that were filtered out had been mislabeled `abandoned` by
+  the outcome heuristic and produced a *false-positive* "cross-flavor abandoned"
+  pattern in the first catalog — now purged. Treat any pre-hardening finding with
+  suspicion.
+- **Key framing:** all 27 real sessions ended in `success`. So the friction here
+  is **cost/efficiency, not failure** — sessions get there, but pay an avoidable
+  tax to do it.
+
+## The headline number
+
+Across the 27 real sessions, tool-call activity breaks down as:
+
+| Bucket | Share |
+|--------|------:|
+| shell (Bash / run_terminal) | 38.2 % |
+| edit | 30.2 % |
+| read | 12.9 % |
+| **State Hub MCP** | **10.3 %** |
+| **task-management plumbing** | **5.8 %** |
+| **schema-loading (`ToolSearch`)** | **1.5 %** |
+| other | 1.1 % |
+
+**~17.6 % of all tool calls in real coding sessions are coordination plumbing
+(hub + task + schema-loading), not touching the repo.** Per-session infra-overhead
+share: median **11.7 %**, p90 **26.1 %**, max **43.3 %** — it concentrates badly.
+
+## Ranked friction
+
+### 1. State Hub call volume — *highest cost, addressable*
+State Hub MCP is 10.3 % of all tool calls and dominates the worst sessions:
+
+| Repo (one session) | total calls | State Hub calls | overhead share |
+|--------------------|------:|------:|------:|
+| vergabe-teilnahme | 570 | **231** | 43 % |
+| activity-core | 488 | 98 | 23 % |
+| flex-auth | 236 | 35 (+27 task) | 29 % |
+| net-kingdom | 129 | 25 | 22 % |
+
+Root cause: many **fine-grained** calls — per-task status updates, per-event
+progress writes, repeated `get_domain_summary`. 231 hub calls in a single session
+is coordination overhead, not work.
+
+### 2. Schema-loading thrash (`ToolSearch`) — *low cost, near-zero-effort fix*
+**106 `ToolSearch` calls across 22 of 27 sessions (81 %).** The State Hub MCP
+tools are *deferred*, so nearly every session re-discovers and re-loads the same
+tool schemas before it can call them. This is pure overhead with no work value —
+and it is **exactly the CLI/MCP-interface friction hypothesized.**
+
+### 3. Task-management plumbing — 5.8 %
+`TaskUpdate` / `TaskCreate` / `todo_write` / `update_task_status`. Overlaps with
+(1); much of it is redundant status churn within a session.
+
+### 4. Tool thrash — *session-shape, watch only*
+11 sessions hammer a single tool 80–230× (usually Bash or Edit). Less an infra
+problem than a sign of missing higher-level tooling; low priority.
+
+### 5. Budget overrun — 3 sessions
+Token cost well above peers. Secondary; revisit once (1)–(2) are addressed.
+
+## Recommendations
+
+**The CLI/MCP-interface hypothesis is validated as a top-2 friction, not a minor
+issue.** Two high-ROI moves:
+
+- **A. A State Hub skill (highest ROI).** A skill (or a pre-loaded tool manifest)
+  that (i) **front-loads the common hub tool schemas** so agents stop
+  `ToolSearch`-ing for them — eliminates finding #2 almost entirely (81 % of
+  sessions) — and (ii) **teaches batched writes** (sync N task statuses in one
+  call, fewer progress events) to attack finding #1. Low effort, broad reach.
+- **B. Coarser hub operations.** Add bulk endpoints / a single "sync workplan
+  statuses" op so a session doesn't make 200+ individual hub calls. This is the
+  structural fix behind the skill's guidance.
+- **C. Measure the effect (Phase 4).** After A/B land, compare infra-overhead
+  share on subsequent sessions against this baseline (median 11.7 %, p90 26.1 %).
+  This is precisely what the Measure phase is for — the loop closes here.
+
+## Content-level root causes (error-body mining)
+
+*Added 2026-06-07 from [AGENTIC-WP-0006] — `build_digest` now mines normalized
+error fingerprints into the durable digest, and `sig_recurring_error` clusters
+them. This is the "why" the tool-mix view above could not see.*
+
+**26 of 27 real sessions hit at least one error.** Top recurring error
+fingerprints across the corpus (by # sessions affected):
+
+| # sessions | occ | flavors | top sample |
+|-----------:|----:|---------|------------|
+| **12** | 32 | claude | `<tool_use_error>File has not been read yet. Read it first before writing to it.` |
+| **6** | 13 | claude | `<tool_use_error>File has been modified since read …` |
+| **4** | 9 | **claude + grok** | `make: *** [Makefile:227: fix-consistency] Error 1` |
+| 3 | 21 | claude | `MCP error -32602: Invalid request parameters` |
+| 3 | 6 | claude | `Error calling tool 'update_task_status': 'title'` |
+| 2 | 6 | claude | `make: *** [Makefile:21: test] Error 1` |
+
+Reading:
+
+- **#1 — Edit/Write-before-Read (12/27 sessions, 8 repos).** The single most
+  common error is agents trying to edit a file they haven't read into context.
+  This is a *workflow* friction, highly addressable: a Read-before-Edit reflex in
+  the agent instructions / a skill, or a harness affordance. (Observed live: the
+  author hit this exact error twice while writing this workplan.)
+- **#2 — stale-read conflicts (6 sessions):** "File has been modified since read"
+  — same family, a re-read-before-edit discipline fixes both.
+- **#3 — cross-flavor `make fix-consistency` failures (claude + grok, 3 repos):**
+  the consistency tooling itself fails across flavors — a shared infra issue worth

+(ADR-004: `.kaizen/metrics/<agent>/executions.jsonl`). The two layers correlate

+

+(kaizen-agentic). Field mapping from `Session.session_uid` → `helix_session_uid`,
+`digest.cost` → `tokens`, `tool_histogram` MCP share → `infra_overhead_share`.
+
+**Read path:** `kaizen-agentic metrics correlate <uid>` looks up a digest via
+`HELIX_STORE_DB` (this repo's session store). No write path from kaizen-agentic
+into Helix Forge.
+
+**Related kaizen-agentic docs:** [ADR-004 project metrics convention](https://gitea.coulomb.social/coulomb/kaizen-agentic/src/branch/main/docs/adr/ADR-004-project-metrics-convention.md),

+### 11.1 Session-close env export (dual-layer agents)
+
+Agents that run **both** Helix Forge capture and kaizen `metrics record` should
+export the following **after** the ingest sweep has written the session digest
+(`python -m session_memory.ingest` or an equivalent Stop/SessionEnd hook). Names
+match kaizen-agentic ADR-004 — do not invent parallel aliases.
+
+| Variable | Source in Helix Forge | Purpose |
+|----------|----------------------|---------|
+| `HELIX_SESSION_UID` | `Session.session_uid` | Primary correlation key → `helix_session_uid` |
+| `HELIX_REPO` | `digest.repo` | Project/repo scoping |
+| `HELIX_FLAVOR` | `digest.flavor` | Agent runtime (`claude` / `codex` / `grok`) |
+| `HELIX_TOKENS` | `digest.cost.input_tokens + digest.cost.output_tokens` | Token rollup → `tokens` |
+| `HELIX_INFRA_OVERHEAD_SHARE` | infra bucket share over `tool_histogram` (see `measure.metrics.session_metrics`) | MCP/plumbing overhead → `infra_overhead_share` |
+
+Example (after digest exists):
+
+```bash
+export HELIX_SESSION_UID="claude:abc-123"
+export HELIX_REPO="agentic-resources"
+export HELIX_FLAVOR="claude"
+export HELIX_TOKENS=125000
+export HELIX_INFRA_OVERHEAD_SHARE=0.117
+# optional — lets kaizen correlate without guessing the store location:
+export HELIX_STORE_DB="$(pwd)/session_memory/.store/mem.db"
+kaizen-agentic metrics record   # merges HELIX_* when present
+```
+
+### 11.2 Digest store location and read API
+
+- **`HELIX_STORE_DB`** — absolute path to the SQLite file holding Tier 2 digests.
+  Defaults to `config.toml` `[store].db_path` (`session_memory/.store/mem.db` relative
+  to the repo root). Export as an absolute path when setting the variable on session
+  close so `metrics correlate` works across hosts and working directories.
+- **Thin CLI** — `python -m session_memory.digest_lookup <session_uid> [--json]`
+  prints one digest without running ingest. Exit `0` on hit, `1` when missing.
+- **Programmatic** — `Store.get_digest(session_uid)` returns the JSON blob written
+  by `build_digest` / `analyze`.
+
+**Stable digest JSON shape** (fields consumers may rely on):
+

+  (FR-A3); blocks carry stable `BEGIN/END` markers so re-running updates in place.

+  `distribute/active_patterns.json` records which pattern+version is proposed in
+  which `(repo, flavor)` (FR-X4).
+
+## Measure effectiveness (closing the loop)
+
+Track whether the fleet is getting cheaper / more reliable, and whether a
+distributed pattern actually helped.
+
+```bash
+python -m session_memory.measure --label "baseline"      # snapshot + trend

+  retired. Recorded pre-fix baseline (2026-06-07): 27 sessions, infra-overhead
+  median 11.7 %, error rate 0.96, schema-thrash 8 sessions.
+
+## Weekly retro (the input to the scheduled retrospection)
+
+A windowed roll-up: detect + measure over the last N days → the **top-3
+improvement suggestions per repo** (cross-flavor first; recommendations pulled
+from the Pattern Catalog) → published to the hub as the `coding_retro` read model.
+
+```bash
+python -m session_memory.retro                      # last 7 days, local report
+python -m session_memory.retro --window-days 30 --json
+python -m session_memory.retro --publish            # also post coding_retro to the hub

+

+`event_type=coding_retro` progress event. This is consumed by activity-core's
+**Weekly Coding Retrospection** schedule (ACTIVITY-WP-0008, Saturday 19:00 Berlin),

+# Coding Session Memory — Detect Hardening
+
+A focused hardening pass (call it Phase 1.5) so the Detect output is trustworthy
+enough to drive an **infrastructure assessment**. Triggered by ad-hoc analysis of
+the live store after Phase 2:
+
+- Of **72 captured sessions, only 31 are real coding sessions**; the rest are
+  health-checks / smoke-tests / interrupted runs (mostly `llm-connect` *"Say hello
+  in one word"*). The `abandoned` outcome heuristic mislabels these, and Phase 2
+  cataloged a **false-positive** "cross-flavor abandoned" pattern as
+  `approved`/`distribution_ready`.
+- All 31 real sessions read as `success`, so the current signal set
+  (outcome + markers + cost) surfaces almost no genuine friction.
+- The already-captured `tool_histogram` tells the real story: **~17% of tool
+  activity in real sessions is State Hub MCP + task plumbing + `ToolSearch`
+  schema-loading**, concentrated to 40–70% in some sessions — but `signals.py`
+  never looks at it.
+
+No new capture is needed — this is analysis the data already supports.

+# Coding Session Memory — Error-Body Mining
+
+The friction assessment ([ASSESSMENT-infra-friction.md](../docs/ASSESSMENT-infra-friction.md))
+can see *that* a session was expensive (tool-mix, cost, overhead share) but not
+always *why* at the content level — the specific error messages and repeated
+failed approaches. The digest captures tool histograms and prompt/response
+snippets, but **not error-body text**. This workplan closes that gap so Detect can
+surface recurring root-cause errors, not just coarse markers.
+
+Approach: capture **normalized error fingerprints + samples into the durable Tier 2
+digest** (raw Tier 1 blobs are evictable, so mining must persist into the digest),
+then cluster recurring fingerprints across sessions into candidate problem
+patterns through the existing clusterer. No new capture source — this reads the
+event/blob bodies already ingested.

+
+Extend `core/digest.py` `build_digest` to extract, from failed events
+(`kind=error` and `tool_result` bodies matching the existing `_FAIL_HINTS`), a
+**normalized fingerprint** (strip paths, line numbers, UUIDs, hex) plus a short
+sample, stored as `digest["error_snippets"] = [{fingerprint, sample, count, tool}]`.
+Same error across a session collapses to one fingerprint with a count. Durable in
+Tier 2 (survives Tier 1 eviction). Bump `SCHEMA_VERSION`. Unit-tested on synthetic
+sessions with repeated and varied errors.

+
+Add `detect/signals.py` `sig_recurring_error` keyed on the error fingerprint, so
+the same error recurring across sessions/repos/flavors clusters into a candidate

+# Act on #1 Friction — Read-before-Edit Reflex
+
+The error-body mining ([AGENTIC-WP-0006](AGENTIC-WP-0006-error-body-mining.md))
+found that the single most common error across real coding sessions is
+**`File has not been read yet. Read it first before writing to it.`** — Edit/Write
+before Read, in **12 of 27 sessions across 8 repos** — followed by the stale-read
+**`File has been modified since read`** (6 sessions). See
+[ASSESSMENT-infra-friction.md](../docs/ASSESSMENT-infra-friction.md).
+
+This is the cheapest high-value fix surfaced by the whole analysis: a short
+behavioural reflex in the agent instructions. We also capture it as a curated
+SolutionPattern so Phase 3 Distribute can propose it to other repos/flavors —
+closing the assess → curate → distribute loop by hand for one real pattern.

+# Helix Forge ↔ kaizen-agentic Correlation — Doc Links and Session-Close Contract
+
+**Coordination trigger:** State Hub inbox from `kaizen-agentic` (2026-06-15) after
+KAIZEN-WP-0004 — ADR-004 correlation layer is live on the project-metrics side.
+This repo already has a partial link in `docs/DESIGN-session-memory.md` §11 (commit
+`a66d502`). Remaining work is bidirectional surfacing, a session-close env-export
+convention for agents using both layers, and a stable read-path for
+`kaizen-agentic metrics correlate`.
+
+**Boundary:** link-by-reference only — no ingestion or write path from kaizen-agentic
+into Helix Forge. Authoritative cross-repo contract stays in kaizen-agentic:
+`docs/integrations/helix-forge-correlation.md`.
+
+## Bidirectional Doc Links and Stale Design Footer
+
+```task
+id: AGENTIC-WP-0011-T01
+status: done
+priority: high
+state_hub_task_id: "616ec197-58ce-4de0-bb7b-1c4a3f9a1e24"
+```
+
+Complete the bidirectional documentation surface requested by kaizen-agentic:
+
+- Add a **Project metrics correlation** subsection to `docs/PRD-helix-forge.md`
+  (ecosystem integration / downstream consumers) linking to DESIGN §11 and the
+  kaizen contract doc.
+- Add a short **Correlation with kaizen-agentic** section to
+  `session_memory/README.md` (two-layer model, link to contract, no re-implementation).
+- Remove or replace the stale DESIGN §11 footer (*"Next step: AGENTIC-WP-0002"*) —
+  Phase 0–4 and retro are finished.
+
+## Session-Close Env Export Convention
+
+```task
+id: AGENTIC-WP-0011-T02
+status: done
+priority: high
+state_hub_task_id: "1c20d5fa-83c2-46c7-b21e-be1ea241bae6"
+```
+
+Document the recommended environment export at session close for agents that run
+**both** Helix Forge capture and kaizen `metrics record`. Cover at minimum:
+
+| Variable | Source (Helix Forge) | Purpose |
+|----------|----------------------|---------|
+| `HELIX_SESSION_UID` | `Session.session_uid` after digest write | Primary correlation key |
+| `HELIX_REPO` | session `repo` field | Project/repo scoping |
+| `HELIX_FLAVOR` | session `flavor` | Agent runtime (claude/codex/grok) |
+| `HELIX_TOKENS` | `digest.cost` totals | Token rollup for project metrics |
+| `HELIX_INFRA_OVERHEAD_SHARE` | MCP/tool histogram share | Infra overhead attribution |
+
+Place in DESIGN §11 (canonical spec) and a concise operator note in
+`session_memory/README.md`. Align field names with kaizen-agentic ADR-004 mapping
+table — do not invent parallel names.
+
+## Stable Digest Read Path for `metrics correlate`
+
+```task
+id: AGENTIC-WP-0011-T03
+status: done
+priority: medium
+state_hub_task_id: "80e35324-d46e-4737-88e7-0316088e7ace"
+```
+
+Give `kaizen-agentic metrics correlate <uid>` a stable, documented read convention
+across hosts:
+
+- Document `HELIX_STORE_DB` defaulting to `session_memory/.store/mem.db` (from
+  `config.toml` `[store].db_path`, absolute path when exported).
+- Document the existing `Store.get_digest(session_uid)` JSON shape consumers may
+  rely on (outcome, cost, tool_histogram, repo, flavor, timestamps).
+- Add a thin read entrypoint — e.g. `python -m session_memory.digest_lookup <uid>`
+  or `python -m session_memory.store --digest <uid> --json` — that prints one
+  digest without running a full ingest sweep. Unit-test the CLI; no new runtime
+  dependencies.
+
+After workplan updates, notify the operator to run from `~/state-hub`:
+
+```bash
+make fix-consistency REPO=agentic-resources
+```
+
+Mark the kaizen-agentic inbox message read once T01 is merged or the workplan is
+filed (coordination ack).
